Relation between oscillation frequency and LCD frame frequency
Set Output PWM waveform of LED1 to LED3 terminal, shown below:
- LED1 PWM Phase set D1=0, D0=0
- LED2 PWM Phase set D1=1, D0=0
- LED3 PWM Phase set D1=1, D0=1
- PWM Frequency set / OSC ON/OFF / Output port ON/OFF
D4=0, D3=1, D2=1, D1=1, D0=1
- LED1 to 3 PWM Data Set
(PWM 4, PWM 3, PWM 2, PWM 1, PWM 0) = (1,0,0,0,0)
